DIAGNOSIS is a journey into the depths of subconscious of a city formed by human beings. The inhabitants of this city undergo the sessions on the couch. Unlocked by formally trivial questions, they begin their journey into the depths of their own feelings and emotions towards the place where they live. The city itself is only a starting point. Over time, conversations get more and more intimate. The scenes from life, reminiscences and highly emotional moments interlace with the subjectively perceived shots of the city. They are blending together, complementing and interacting with each other. The fears of the film characters, their desires and unfinished affairs become the narrative axis of the film by constituting a common fate.
